范例
Example #1 MongoDB\Driver\Exception\WriteException::getWriteResult() example
<?php$manager = new MongoDB\Driver\Manager('mongodb://localhost');$bulk = new MongoDB\Driver\BulkWrite;$bulk->insert(['_id' => 1]);$bulk->insert(['_id' => 1]);try { $manager->executeBulkWrite('db.collection', $bulk);} catch (MongoDB\Driver\Exception\WriteException $e) { $writeResult = $e->getWriteResult(); if ($writeConcernError = $writeResult->getWriteConcernError()) { var_dump($writeConcernError); } if ($writeErrors = $writeResult->getWriteErrors()) { var_dump($writeErrors); }}?>
以上例程的输出类似于：
array(1) {
[0]=>
object(MongoDB\Driver\WriteError)#5 (4) {
["message"]=>
string(70) "E11000 duplicate key error index: db.collection.$_id_ dup key: { : 1 }"
["code"]=>
int(11000)
["index"]=>
int(1)
["info"]=>
NULL
}
}
